DAVID A. STRAUSS, OF MILWAUKEE, WISCONSIN.

FASTENER FOR STORM-SASHES, WINDOW-SCREENS, &e.

Application filed March 8, 1918.

To all whom it may concern:

Be it known that I, DAVID A. S'rnAUss, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Fasteners for Storm-Sashes, WVindow-Screens, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in fasteners for storm sashes, window screens and the like.

The principal object of my invention is to provide a simply constructed and ellicient locking means for holding such swinging objects as storm sashes and window screens in a closed position in engagement with stationary members.

A further object of the invention is to provide an efficient means for retaining the storm sash, window screen or the like in a position spaced from the window casing.

With these and other objects in view, the invention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed and shown in the drawing wherein:

Figure 1 represents a side elevational view of a portion of a window casing and storm sash having my invention applied thereto.

Fig. 2 is an enlarged detail elevational view of the invention in locking position.

Fig. 3 is a vertical sectional view of the parts shown in Fig. 2.

Fig. 1 is a detailed transverse sectional view showing more particularly the construction of the latch or stay bar and its keeper.

As disclosed in the accompanying drawing, wherein similar reference characters indicate like parts throughout the several views, the numeral 1 denotes a window frame of any ordinary or preferred construction having a storm sash or screen frame 2 hinged thereto at its upper end. The invention is designed to either space the swinging storm sash or screen frame, as the case may be, from the window casing as in Fig. 1, or to lock the former to the latter as in Figs. 2. and 3.

Referring more particularly to the invention, 3 indicates a latch or stay bar which is pivoted by means of a pivot pin .tbetween spaced ears 5 of a bracket 6. The bracket Specification of Letters Patent.

Serial No. 221,275.

is preferably secured to the storm sash or screen frame 2 by screws or the like 7. The latch bar in the present instance is provided with a pair of slits 8 adjacent one end and the material between the same is bowed outwardly in one direction, while that between the slits and the outer side edges of the bar is bowed in the opposite direction to form a bearing for said pivot pin 4.

The opposite or free end of the latch bar 3 is provided with a transverse slot 9 for engagement with the upstanding tongue 10 of a right-angular keeper 11. One flange of the keeper forms an attaching member for securement to the window casing, and the tongue 10 is formed on the other flange. Thus when it is desired to space the storm sash or window screen as in Fig. 1, the slot 9 is engaged with the keeper.

On the other hand when the storm sash or the like is to be locked in closed position and in engagement with the window easing, the latch bar hangs downwardly from its pivot pin and engages the inner face of the locking flange of the keeper 11. In other words said locking flange is disposed between said latch bar and the storm sash or the like. WVhen so positioned the bracket 6 is immediately adjacent the keeper 11, the tongue 10 of the latter being disposed between said ears 5.

By retaining the latch bar as in Fig. 3 it is obvious that it will be impossible to move the storm sash or the like outwardly away from the window casing. Therefore, I provide a finger 19. which projects from the latch bar adjacent its pivot and at substantially right angles thereto, and a resilient stop in the form of a leaf spring 13 for engagement with the end of said finger. The spring 13 is slightly V-shaped and is secured at one end only to the bracket 6 by one of the screws or the like 7 The highest point or apex of the spring is in a horizontal plane slightly. above the similar plane of the pivot pin 4%, and projects theretoward to such an extent as to cause the end of the finger 12 to engage therewith when the parts of the invention are in their locking positions.

In moving the storm sash or the like from its open position to its closed or locked position, the latch bar is lifted slightly to disengage its slotted end from the keeper, whereupon the former will slide over the tongue 10 of the latter until the window casing is engaged by the storm sash. The operator now forcibly moves the latch bar 3 from a substantially horizontal position to a vertical position inwardly of the keeper member 11. 1 Such movement causes the end of the finger 12 to forcibly engage the spring 13 and ride past the apex thereof. Owing to the fact that the finger is continuously engaged by thespring, it is obvious that the latch bar will be normally urged toward the keeper 11. Similarly it will be seen that any tendency to move the storm sash or the like away from the window casing will increase the forcev with which the latch bar is urged toward the keeper in View of the fact that the end of the finger is being brought closer to the apex .of' the spring. In other words,

in order to unlock the parts it is necessary to move the latch bar upwardly.

A novel provision is made for retaining the latch bar in slidingengagement with the tongue of the keeper during the movement of the storm sash or the like to open or closed positions. This arrangement will be seen most clearly from Fig. 4 wherein it will be noted that although the latch bar is longitudinally straight, it is. transversely curved or substantially semi-circular. The tongue 10 is of similar shape and therefore side play of the latch bar relative thereto is prevented.

I claim:

1. The combination with a stationary member and a swinging member movable toward and away from the stationary member,'of a bracket secured to the swinging member and having outstanding ears, a bar having by said finger for holding the bar in posi tion with the keeper conlined between said bar and the swinging-member; 2. The combination with'a stationary member and a swinging member movable toward and away from the same, of means for-retaining the swinging member in open position including a stay bar pivoted to one of the members, said bar being substantially longitudinally straight nd transversely curved to form a channel, and ,a keeper car ried by the other member for engagement with the free end of the bar, the end ofthe keeper being curved to slidably engage in the channel of the bar when the swinging member is moved toward or away from the stationary member.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
